Theoretical and experimental investigation of the force of the pad friction of the brake disc

Abstract

The braking is an extremely important stage in the running of a railway vehicles as fas as the safety of traffic is concerned due to the multitude and diversity of factors that may influence it. The disk brake was first mounted on the passenger cars designed for the suburban traffic, while at present it acts as a main brake in the high speed trains that run along the high speed railroads in Europe and all over the world. The paper presents theoretical and experimental results on the forces produced between coupling elements of the disc brake friction (the pads-brake disc). So, after a theoretical calculation of distance (a), from the brake disk centre at which force Fs has to apply so as to generate an approximately even wear of the friction lining in this paper it is presented a force cell designed and produced by the author in order to experimentally
